Darwin Algae Eating Shrimp?


Crabby

Recommended Posts

Hey guys, just found an add for this website showcasing a cool-lookin native algae eating shrimp.
https://algaeeatingshrimp.com.au/products/australian-algae-eating-shrimp

Anyone heard of these before or own any? My interest was peaked by the claim that they eat hair-type algae, as I have some on my crypts and lace fern that I cannot remove. And for a price of $4 ea, and super easy parameters, they sound pretty doable! 
Tell me more oh great SKFians! ?

(or feel free to point me towards an already existing page)

post-note: have you/do you keep these grubs? Seems like your sort of thing.

The photo is not a DAS.  The only place I know that breeds DAS commercially is Aquagreen  for half that price.  https://www.aquagreen.com.au/catalog.html

I do keep them and have bred them in the past but I don't have any excess at the moment.  I'm going to try and breed them again this summer.  They have marine larvae so are not easy but on the flip-side they live for 5 years or more and are hardy.

The photo at that site looks to be a Paratya  which will also eat filamentous algae but not as voraciously as DAS.  My Paratya came in the mail from https://www.livefish.com.au/tropicals/shrimp-and-crays.html

You can get them in local rivers but I find the ones from livefish do better in warmer tanks (Livefish are in QLD) - these breed in fresh water in your tank (easily).

Oh cool I've seen paratya locally as well, just a baby one tho, barely noticed him. Do they stay totally clear or have some different colours? 

And in terms of the DAS (as I think they are super cool), will they still thrive in freshwater? And how large do they grow? (I have a big grumpy apisto who might have a meal of any small shrimp - tho I'm getting rid of him soon possibly)

And for both of them, if I wanted to put them in with my TTS would they interbreed?

Thanks Grubs!

What Grubs said.

DAS is a little bit more colourful as well. You can get them at Aquagreen but just remember, they need brackish water and the plankton in it to breed. Or more accurately the newly hatched young need brackish water.

Yeah not planning on doing a breeding project just yet. Maybe late 2020, but not any time soon. If I were to get them I would just need to know that they will not fertilise my female tts.

female tts.

tts as in Tangerine Tiger?

Hmm, no guarantees. they are both Caridina afterall.

Yeah tangerine tiger shrimp. I don’t think I would even mind that much if they procreated cuz I NEED MORE SHRIIIIIIMP!!!! 

(And the offspring would be cute)

Do they require much skill to take care of? (Either)

No nothing special. Just get them the right water parameters and that's it.

@Grubs might have the perfect water parameter requirements for DAS, so see if he can list them.

Otherwise, I used to keep DAS in water that was ph6.8 - 7.0, KH 4, GH6 and TDS of 200-230 and 25DegC. 

These shrimp from QLD seem to handle slightly higher temps.

Idk my tds but the rest sounds similar to my tap. If Grubs uses just dechlorinated tap water too then we probably would have the same parameters as we’re both in melb. And that’s my normal temp as well. 
How do you keep them @Grubs?

DAS are very robust and I've kept them in a tank with Melbourne tap water and in rainwater with  DIY hardness booster.  You'll find them in Northern Australia in both the fresh and brackish sections of rivers so they have really wide tolerances.  My tanks range from 24C to 29C

If you get some keep the covers on for the first 2 weeks as they can be jumpy if your water parameters are a long way from what they were housed in. After a couple of weeks they settle down and rarely jump.  I know some people with open tanks put gladwrap over the top for the first couple of weeks only.

I'll also suggest that no-way will they interbreed with your Tangerine Tigers -  they are very different shrimp and their bits wont fit together even if they were so inclined.

 

If money is tight then Paratya are about half the biomass but will breed up easily and also wont cross with the TT .... or do both.  You can keep all three together in the same tank.

Definitely tempting me here. ? 

What do you feed them? As I currently feed my fish, and hope the shrimp get the leftovers. I’m looking more towards trying to feed my shrimp specifically though. I’ve tried zucchini and spinach, but only the hated snails will eat those. And rarely do I see a shrimp on an algae wafer. They all seem to be doing fine though, so I guess there's enough algae and biofilm for them to eat.

And if I were to get more shrimp with the possible intent of breeding them (not the das of course), would you recommend the removal of my Apistogramma pair? They’re beautiful and I would love to see them breed at some stage, but the are active and the male in particular is quite large. They can get a bit aggressive at times.

Hell Yeah! Apistos will snack on shrimps like there is no tomorrow.

 

There are so many things you can feed your shrimps. Go have a read of a few posts in the "food & nutrition" subforum.

Dang I thought u might say that... for some reason the guy at my rlfs (relatively local fish store) recommended them instead of honey gouramis as a bit of a feature fish. Are there any other ‘feature fish’ style fish that wouldn’t munch on my shrimp, or should I just stick with my endler trio?

I’ll check out the food stuff, thx.

Just an fyi don't buy from this website mentioned by op, they're scammers they take your money and don't deliver, i purchased some shrimp from them and they didn't ship, or return emails etc, had to get a refund from paypal.

I have just been burnt by the same site, no response, no shrimp. I didn't use paypal so I might be out $60. A complete scam.

If you paid via card do a claim with your bank, i also reported this website to shopify and they said they'd investigate, maybe we should report this to scam watch, i have the websites mobile number they registered with paypal too

Edit: I've filed a report with scam watch Australia and cyber crimes

      Good to have an update and good to hear you are getting shrimplets, so hopefully your colony will continue and you may not get to the point where you have to cull some to stop over population. These type of shrimp only live 12 - 18 months so the adult deaths may be natural? If you have the time I would do weekly 25% water changes, adding the new water via a drip system and do some vacuuming clean of the substrate each week, even if only a different bit each week! See if that helps in a few months and if it does then stick with that regime? It should help reduce any build-ups that may be occuring!

      Hello again, much belated update: The tank still has "cycles" of 1-2 month "good streaks" where everybody seems to be doing well, and then a bad streak where the short antenna problem shows up again, and a shrimp dies once every few days.  I am not sure what causes things to go bad, but usually over the course of a few days I will start to see more shrimp quietly standing on the HMF filter, and so I know something is wrong.  Since I am not "doing anything" besides the regular 1-2 week water changes, I just assume that something bad is building up.  Here's a list of things that I've tried that are supposed to be "can't hurt" but didn't prevent the problem either: Dose every other day with Shrimp Fit (very small dose, and the shrimp seem to like it) Sotching Oxydator Seachem Purigen to keep the nitrates lower Keeping the pH below 5.5 with peat Things that I don't do often, so could possibly "reset" the tank back to a good streak, are gravel vac and plant trim, so maybe time to try those again. One other problem I used to have was that sometimes a shrimp would suddenly stop eating with a full or partially full digestive tract that doesn't clear out, and then the shrimp will die within a few days.  I suspected it was one of the foods in my rotation - Shrimp Nature Infection, which contains a bunch of herbal plant things.  I've had this in my food rotation for a few years now and generally didn't seem to cause problems, but I removed it from the rotation anyway.  I don't have a lot of adult Golden Bees at this point so I can't really tell if it worked or not. Overall the tank is not too bad - during the good streaks occasionally a shrimp will get berried and hatch babies with a 33-50% survival rate.  So while there are fewer adults now, there are also a bunch of babies roaming around.  I guess this tank will stagger on, but I really do need to take the time to start up a new tank.  (or figure out the problem)

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony. 
    • sdlTBfanUK
      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!
    • GtWalker97
      Hi SKF!   So I bought some PRL (or at least they were sold as such. These claims are dubious in Australia as people don't know much about the genetics, nor do they care as long as they can make a quick buck). After 8 generations of breeding true, I'm having around 1 in 200 throw a much darker red. They almost look like Red Shadows, but I don't know too much about those types of hybrid. Can anyone help with ID'ing the gene?   TIA (First 2 pics are the weird throws, second photo is their siblings and the last photo is the parents)
